무선 네트워크 카드 mwifiex_usb 인터페이스를 찾을 수 없습니다

한동안 무선 어댑터를 설치하려고 했는데 Surface Pro를 가지고 있는데 ndiswrapper를 두 번 사용해도 "mwlu97w8x64" 드라이버를 로드할 수 없다고 해서 작동을 포기했습니다. 몇년 전 당시엔 문제없이 ndiswrapper로 작동해서 이번에는 맞는 펌웨어를 설치하려고 했는데 ip link나 ifconfig를 하면 mlan(wlan 아님) 인터페이스가 안 뜨고 iwconfig는 더더욱 안 나오네요. /lib/firmware/mrvl/에 펌웨어를 추가했습니다…

올바른 펌웨어가 설치된 상태에서 무선 카드가 작동하도록 할 수 있습니까? 무선 카드를 부팅하기 위해 커널은 무엇을 찾나요? 어떻게 진행하시겠습니까?
